plant that has constant problems can't be hiding good genetics?

its as simple as that. i've been treating a c99 thats been either mag def, or not enough feed. no matter what i do its pale as fuck. so my question is, a plant that has continual problems can't be hiding anything fantastic when it comes to flower or can it?

bump bump bump. its been either mag/nitrogen. the other stablized in flower but i need clones whiting up but still lives. could this pheno of c99 have something good in it? or is it too much of a problem to ever let see the light of day?

tha same thing happened to me with c99s. One of 4 was really slow to veg and I almost tossed it a couple times. i just let it stay in veg an extra month and it finally kicked into gear. Turns out it was the only pineapple pheno I had and a very good yielder. glad i kept it...i still have the mum. if you have the room for it i would keep it
